BACKGROUND : Helicobacter pylori infection leads to gastric mucosal damage by several mechanisms including the direct effect of virulence factors produced by H. pylori, propagation of inflammation, oxidative stress, DNA damage, and induction of apoptosis. ( - ) - Epigallocatechin - 3 - gallate ( EGCG ), one of the green tea catechins, is known to suppress H. pylori - induced gastritis through its antioxidative and antibacterial actions.
